When multiple teams work on the same product, should they have different definitions of "Done"?

Having a unified definition of "Done" across multiple teams working on the same product is crucial for maintaining consistency and quality. A shared definition ensures that all teams adhere to the same standards when delivering increments of work, which is essential for effective integration and collaboration.

When teams have differing definitions, it can lead to misunderstandings about what it means for work to be completed, potentially resulting in code that isn’t fully tested or features that don’t meet the same quality standards. This inconsistency can cause challenges during integration, as products from different teams may not align correctly or may require additional work to meet the overall product quality.

By having a singular definition of "Done," all teams align their understanding and expectations, facilitating better communication, improving coordination, and enhancing the overall ability to deliver a cohesive and high-quality product increment. This practice ultimately supports the Scrum framework's principles of collaboration and transparency, making it a fundamental practice in Agile development.
